Cast die tool of multi-bottom pan and technique for producing multi-bottom pan using the die

Abstract

A die-casting die of a double-bottom pan and a process for making the double-bottom pan by the die-casting die belong to the technical field of casting. The die-casting die comprises a fixed die and amoving die, wherein, the inner surface of the fixed die is provided with a pan body model and an aluminum liquid jet orifice, the inner surface of the fixed die is also provided with positioning seatssymmetrically arranged at the two sides of the pan body model, the two positioning seats are respectively connected with a cylinder at the outside thereof and slide inwards and outwards with the reci procating motion of the cylinder, the inner surfaces of the two positioning seats are corresponding to the outer peripheral wall shape of the pan body model; the inside part of the moving die is provided with a first concave cavity matched with the pan body model and a second concave cavity matched with the two positioning seats, and a 1-6mm gap is kept between the peripheral wall of the first concave cavity and the pan body model. The double-bottom pan made by the die-casting die has the advantages of firm connection, mark-free bottom surface and very nice appearance.

Description

Technical field: [0001] The invention belongs to the field of casting, and in particular relates to a die-casting mold for a double-bottomed pot and a process for manufacturing a double-bottomed pot by using the mold. Background technique: [0002] Because the pot of pure aluminum material cannot be used on the induction cooker, a stainless iron or stainless steel double-bottomed pot has appeared in the prior art to replace. However, the double-bottom pots on the market are generally realized by welding, inlaying, bonding, extrusion molding and other processes. During cold shrinkage, bulges will also occur; moreover, the double-bottomed pots manufactured by the inlay and extrusion molding processes will have joint marks on the bottom surface, and the appearance is not beautiful. At the same time, the two manufacturing processes are very complicated, resulting in the production of products. low efficiency. For this reason, in order to solve these problems, be badly in need ...

Problems solved by technology

However, the double-bottom pots on the market are generally realized by welding, inlaying, bonding, extrusion molding and other processes. These processes generally have the disadvantage of weak connection. During cold shrinkage, bulges will also occur; moreover, there will be joint marks on the bottom surface of the double-bottomed pots manufactured by the inlay and extrusion molding processes, and the appearance is not beautiful. At the same time, the two manufacturing processes are very complicated, resulting in the production of products. low efficiency
